E. coli O26 Outbreak Numbers Hit 45 in 6 States

Forty-five people infected with the outbreak strain of STEC O26 have been reported from 6 states. The majority of illnesses have been reported from Washington and Oregon. The number of ill people reported from each state is as follows: California (2), Minnesota (2), New York (1), Ohio (1), Oregon (13), and Washington (26).

Among people for whom information is available, illnesses started on dates ranging from October 19, 2015 to November 8, 2015. Ill people range in age from 2 years to 94, with a median age of 22. Fifty-eight percent of ill people are female. Sixteen (36%) people reported being hospitalized. There have been no reports of hemolytic uremic syndrome and no deaths.

The epidemiologic evidence available to investigators at this time suggests that a meal item or ingredient served at Chipotle Mexican Grill restaurants at several states is a likely source of this outbreak. The investigation has not identified what specific food is linked to illness. Chipotle Mexican Grill is assisting public health officials with understanding the distribution of food items served at locations where ill people ate and this work is ongoing.

State and local public health officials are interviewing ill people to obtain information about foods they might have eaten and other exposures in the week before their illness started. Forty-three (96%) of 45 people interviewed reported eating at a Chipotle Mexican Grill restaurant. The investigation is ongoing to identify common meal items or ingredients causing illness.

Chipotle E. coli Outbreak – New Numbers

On November 12, the CDC reported fifty ill people from Washington (31) and Oregon (19) from Shiga toxin-producing Escherichia coli O26 (STEC O26) infections. Fourteen people have been hospitalized in Washington (10) and Oregon (4) linked to Chipotle restaurants in Oregon and Washington.

Today the CDC reported that Public health officials in Washington, Oregon, and Minnesota announced that that are continuing the investigation of an outbreak of Shiga toxin-producing Escherichia coli O26 (STEC O26) infections. CDC and the U.S. Food and Drug Administration (FDA) are assisting with the investigation. As of November 17, 2015, 37 people infected with the outbreak strain of STEC O26 have been reported to CDC PulseNet from Washington (24) and Oregon (13). 13 of these people were hospitalized in Washington (9) and Oregon (4). Additional illnesses are under investigation by Washington and Oregon and will be reported if they are confirmed to be infected with the outbreak strain of STEC O26.

There have been no reported infections with the outbreak strain of STEC O26 in Washington or Oregon since the Chipotle Mexican Grill locations closed in the Pacific Northwest on October 30, 2015. A search of the PulseNet database identified one person in Minnesota infected with STEC O26 that has the same DNA fingerprint as ill people in Washington and Oregon. This ill person did not eat at a Chipotle Mexican Grill in the week before illness onset. Minnesota’s investigation is ongoing. The illness does not appear to be linked to Chipotle Mexican Grill locations in Washington and Oregon.

Washington and Oregon report that nearly all of the ill people ate at several locations of Chipotle Mexican Grill in those states before getting sick. The investigation is still ongoing to determine if the ill people ate a meal item or ingredient in common that was served at the Chipotle Mexican Grill locations. Chipotle Mexican Grill reopened its restaurants in Washington and in the Portland, Oregon area that had been closed in response to this investigation.

Chipotle Sickens 50 in Washington and Oregon with E. coli

Fifty ill people have been reported from Washington (31) and Oregon (19). Fourteen people have been hospitalized in Washington (10) and Oregon (4). There have been no reports of hemolytic uremic syndrome (HUS) and no deaths.

Thirty-three isolates from ill people in Washington (22) and Oregon (11) have been uploaded to the CDC PulseNet database. All 33 people were infected with STEC O26 that has the same DNA fingerprint. Additionally, as reported on November 6, a search of the PulseNet database identified one person in Minnesota infected with STEC O26 that has the same DNA fingerprint. This ill person did not eat at a Chipotle Mexican Grill in the week before illness onset. Minnesota’s investigation is ongoing. The illness does not appear to be related to the outbreak in Washington and Oregon linked to Chipotle Mexican Grill locations in those states. Whole genome sequencing, an advanced laboratory technique, is being used to give investigators more information about the DNA fingerprint of the pathogen causing illnesses in Washington, Oregon, and Minnesota.

CDC and state and local public health partners are continuing laboratory surveillance through PulseNet to identify additional ill persons and to interview them. Updates will be provided when more information is available.

The investigation is still ongoing to determine if the ill people ate a meal item or ingredient in common that was served at the Chipotle Mexican Grill locations. Several food items collected from Chipotle Mexican Grill locations in Washington and Oregon are being tested by FDA and Chipotle for the presence of bacteria. As of November 12, 2015, test results have not identified E. coli in any of the food items tested. Additional results are pending and will be reported once available.

83 Tons of Hamburger Recalled Over E. coli

All American Meats, Inc., an Omaha, Neb. establishment, is recalling approximately 167,427 pounds of ground beef products that may be adulterated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

The ground beef items were produced on Oct. 16, 2015. The following products are subject to recall:

80-lb. (approximate weight) boxes of “Ground Beef 80% Lean 20% Fat (Fine Grind)” with Sell By Date 11-03-2015 and case code 62100.
80-lb. (approximate weight) boxes of “Ground Beef 73% Lean 27% Fat (Fine Grind)” with Sell By Date 11-03-2015 and case code 60100.
60-lb. (approximate weight) boxes of “Ground Beef Round 85% Lean 15% Fat (Fine Grind)” with Sell By Date 11-03-2015 and case code 68560.
60-lb. (approximate weight) boxes of “Ground Beef Chuck 81% Lean 19% Fat (Fine Grind)” with Sell By Date 11-03-2015 and case code 68160.
60-lb. (approximate weight) boxes of “Ground Beef Chuck 81% Lean 19% Fat (Fine Grind)” with Sell By Date 11-03-2015 and case code 63130.
80-lb. (approximate weight) boxes of “Ground Beef Chuck 81% Lean 19% Fat (Fine Grind)” with Sell By Date 11-03-2015 and case code 63100.
The products subject to recall bear establishment number “EST. 20420” inside the USDA mark of inspection. These items were shipped to retail locations nationwide.

The problem was discovered on Oct. 30, 2015, when a positive result for E. coli O157:H7 from FSIS’ in-commerce surveillance program testing was traced back to the establishment. There have been no confirmed reports of adverse reactions due to consumption of these products.

E. coli O157:H7 is a potentially deadly bacterium that can cause dehydration, bloody diarrhea and abdominal cramps 2–8 days (3–4 days, on average) after exposure to the organism. While most people recover within a week, some develop a type of kidney failure called hemolytic uremic syndrome (HUS). This condition can occur among persons of any age but is most common in children under 5-years old and older adults. It is marked by easy bruising, pallor, and decreased urine output. Persons who experience these symptoms should seek emergency medical care immediately.

FSIS and the company are concerned that some product may be frozen and in consumers’ freezers.

Consumers who have purchased these products are urged not to consume them.

Chipotle Tied to E. coli Outbreak

Update: AP now reports that Washington and Oregon Health officials are investigating an E. coli outbreak linked to six Chipotle restaurants in Washington state and Oregon, health officials said Saturday. Three people in the Portland area and at least 19 people in Washington have become sick after eating at the Mexican food chain since October 14.

The Skagit Valley Herald reports that the Skagit County Department of Public Health announced Friday that it has closed Chipotle Mexican Grill in Burlington pending an investigation of several E. coli infections among recent diners.

Of five cases under investigation since October 15, four individuals were hospitalized, according to the health department news release. Results of specimens sent to the state health lab for analysis are expected early next week.

The Department of Public Health advised those who have had close contact with someone ill with symptoms of E. coli infection to see a doctor. Symptoms include diarrhea (often bloody), abdominal cramps, vomiting and nausea.

Uncle John’s Old Fashioned Apple Cider Recalled After E.coli Test

The Michigan Department of Agriculture and Rural Development today issued a consumer advisory for Uncle John’s Old Fashioned Apple Cider produced by Uncle John’s Cider Mill located at 8614 US-127 in St. Johns, MI, because it has the potential to be contaminated with Shiga-toxin producing E. coli bacteria. Consumers who have purchased this product at Uncle John’s Cider Mill are urged not to consume it and dispose of the product immediately.

A routine, random sample collected by an MDARD food inspector tested positive for the Shiga-toxin producing E. coli by the department’s Geagley Laboratory. No illnesses have been reported to date. Uncle John’s has voluntarily ceased sales of cider awaiting further test results.

This advisory affects approximately 1,200 gallons of cider produced on October 17. The cider was sold at the cider mill from the retail cooler, packaged in various sized plastic jugs with a sell by date of October 30, 2015; or served directly to consumers by the cup as cold cider, frozen cider slushes and hot cider, from October 18 through October 21.

The E. coli symptoms  vary by individual, but often include severe stomach cramps, diarrhea (often bloody), and vomiting. If there is fever, it usually is not very high (less than 101˚F/less than 38.5˚C). Most people get better within 5–7 days. Some infections are very mild, but others are severe or even life-threatening. Around 5–10% of those diagnosed with Shiga-toxin producing E.coli infections develop a potentially life-threatening complication known as hemolytic uremic syndrome. Signs that a person is developing HUS include decreased frequency of urination, feeling very tired, and losing pink color in cheeks and inside the lower eyelids. Persons with HUS should be hospitalized because their kidneys may stop working and they may develop other serious problems. Most persons with HUS recover within a few weeks, but some suffer permanent damage or die. People experiencing these problems should seek immediate medical attention.
